Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems: Christian Borntraeger discovered an issue effecting the alpha, mips, powerpc, s390 and sparc64 architectures that allows local users to cause a denial of service or potentially gain elevated privileges. Vegard Nossum discovered a memory leak in the keyctl subsystem that allows local users to cause a denial of service by consuming all of kernel memory. Wei Yongjun discovered a memory overflow in the SCTP implementation that can be triggered by remote users. Duane Griffin provided a fix for an issue in the eCryptfs subsystem which allows local users to cause a denial of service (fault or memory corruption). Pavel Roskin provided a fix for an issue in the dell_rbu driver that allows a local user to cause a denial of service (oops) by reading 0 bytes from a sysfs entry. Clement LECIGNE discovered a bug in the sock_getsockopt function that may result in leaking sensitive kernel memory. Roel Kluin discovered inverted logic in the skfddi driver that permits local, unprivileged users to reset the driver statistics. Peter Kerwien discovered an issue in the ext4 filesystem that allows local users to cause a denial of service (kernel oops) during a resize operation. Sami Liedes reported an issue in the ext4 filesystem that allows local users to cause a denial of service (kernel oops) when accessing a specially crafted corrupt filesystem. David Maciejak reported an issue in the ext4 filesystem that allows local users to cause a denial of service (kernel oops) when mounting a specially crafted corrupt filesystem. David Maciejak reported an additional issue in the ext4 filesystem that allows local users to cause a denial of service (kernel oops) when mounting a specially crafted corrupt filesystem.
